TOOL FOR INSERTING RACENAYS Ilil' HUBS AND, HOUSINGS.

" Application filed Januarye, 1921. Serial No. 434,928.

To (til whomiz may concern:

Be it known that I, IIARDEN It. HURLB'UT, a citizen of the United States, residing at l ll'heaton, in the county of Barry and State of Missouri, have invented certain new and useful Improvements in Tools for Inserting Raceways in Hubs a11dIIo11sings;ancl I do hereby declare the following to-be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a tool for inserting raceways in wheels, hubs, and in hous ings such as transmission cases, rear axle constructions of pleasure cars. trucks and tractors, and the like, and more particularly to a tool designed for inserting the raceways in tapered roller bearings, and the A still further object is to provide a device which shall include a spindle or screw shaft, a pair of heads fitting the shaft snugly, but movable longitudinally thereof and a crank nut by means of which the heads are caused to force the raceways into the hub or housing.

A still further object is to provide a plurality of heads serving the purpose indicated and specially formed to permit of use when inserting the raceways of either roller bearings or ball bearings.

With the foregoing and other objects in view, the invention consists in the novel construction, combination, and arrangement of elements hereinafter described and claimed, it being understood that minor changes may be made within the scope of the claims, without departing from the spirit of the invention.

In the accompanying drawing: Figure 1 is a view illustrating the manner in which the device isused in inserting raceways in hubs.

Figure 2 is a view in sideelevation of the device arranged for inserting the raceways of roller bearings.

Figure 3 is a view in side elevation of the device arranged for inserting the raceways of ball'bearings, and

Figure 4c is a sectional view taken on a plane extending centrally and longitudinally through the device.- I i In carrying out'myinvention, I provide a spindle or screw shaft, designated 10 and including a threaded portion 11, a smoothed portion 12 and a similar portion 13 of slightly greater diameter. 14' opposite to the threaded end is of a suitable diameter to provide the requiredst-rength and is provided with a transverse bore 15 through which a tool such as a punch may be inserted, to prevent the turning of the spindle when the device is in operation, or when the raceways are being applied to the hub or housing. The threaded portion of the spindle designated 11 is engaged by a nut 16 having formedtherewith a crank 17, whereby the necessary pressure is applied to the heads referredto below, in forcing the raceways into position.

The'heads are designated 20 and 21, and

each includes a cylinder portion. 22 which The. extreme end g passes into the bore of the hub or housing,

and a cylindrical portion 23 of greater diameter. A tapered portion 24 and, shoulders 25 and 26 complete that portion of the head, that is, of each head, designed for use when inserting a raceway of a roller bearing of the type indicated. Each headis provided with a central. longitudinal bore fit. ting the spindle snugly but permitting longitudinal -movement hereinbefore' indicated.

The heads are maintainedin exact alinement- In the accompanying drawing the tool is shown in position for inserting raceways in the hub of a wheel. The manner n which the tool is used in inserting racewaysin bearing the heads are in the relative position shown in Figure 2 and when applying the raceways of a ball bearing, they then in the relative position shown in ure 3, the screw shaft being threaded a sufficient distance to permit oi either position. The crank nut is turned to force the heads toward each other and iereby force the cups or raceW-avs into position in the hub or housing, ali elements maintaining exact alineinent during the operation, as distinguished from the angular movement neces sarily involved in inserting the raeeways by the use of hammer and punch.

Having thus described inv invention What I claim is:

1. A device ofthe class described havinga spindle, reversible heads on said spindle, said heads being ol dili'erent shape at each end an abutment on the spindle for one of said heads and meansoperable on the spindle against the other head to urge movement of one head toward the other head.

2. A device of the class described having a spindle, heads on said spindle one slidable relatively to the other and said heads being or different shape at each end and reversible for the purpose soeciiied.

In testimony whereof i affix my signature in presence tWo Witnesses. I
